I believe you have compiled with the PGI compiler. As a first try, you can do the following:

- Find out where the compiler is installed (/opt , /usr) on your system.- export (or setenv if you have csh) LD_LIBRARY_PATH=<path to pgi lib>:$LD_LIBRARY_PATH e.g. export LD_LIBRARY_PATH=/opt/pgi-6.1/lib:$LD_LIBRARY_PATH

After this you can check by issuing command : ldd geogrid.exeThis will list all the libraries required by geogrid during execution and the path on your system where it occurs. There shouldn't be any library with "not found" in front of it.

If the problem still persists with the same libpgc, there could be an issue with the compiler/ compiler settings.
